What Do Oil Additives Do For Your Engine?

There has always been debate among car enthusiasts and technicians about whether or not oil additives are beneficial to your vehicle. Some people think oil additives are a waste of money, while others swear by them because they increase performance and extend engine life. Professionals that utilize oil additives claim to see improvements in gas mileage, maintenance intervals, and engine quietness. But is spending money on motor oil additives really a good investment?

In this article, we will be taking a look at what oil additives do for your engine and deciding whether or not they are beneficial to your vehicle.

What Oil Additives Do For Your Engine?

Approximately 15% of most motor oils contain additives. Without these additives, the oil cannot effectively perform its vital functions to keep your engine running. Over time, oxidation, and degradation can cause your oil to deteriorate. As engine oil ages, it might lose some of its additives. Without the right quantities of these additives, you risk greater engine damage, which might lead to rust, corrosion, oil sludge, poor fuel efficiency, unwanted car failure, overheating, and costly engine repairs.

The Benefits Of Oil Additives

High-quality oil additives can minimize engine damage that occurs over time, increase the vehicle’s lifespan, and boost its overall performance. Although different types of oil additives offer different benefits, the following are the most significant ones: 

  1. Reduces engine wear and tear

More than 75% of a vehicle’s engine’s degradation takes place during startup. By covering parts and surfaces and reducing friction to prevent excessive wear and tear, engine oil additives help engines run at peak performance. Damage can also do a number on your pistons, which is why you need oil additives to reduce engine knocking noise to ensure a smooth driving experience.

  1. Enhances seals and prevents leakage 

You may need to do more than just routine maintenance to keep an older car’s engine running smoothly. Engines with known problems can benefit a lot from oil additives. Cracks or other damage from regular wear and tear can cause fuel leaks. Oil additives prolong the life of fuel lines and fittings, allowing them to do a better job of keeping fuel where it belongs (in the tank).

  1. Helps prevent corrosion

Many are not aware of this, but there is acid in engine oil, and too much of it can eat away at your engine. These days, additives are commonplace in most oils to prevent acid accumulation. However, after some time, the tainted oil can become dangerous to your engine. To prevent any further damage to the engine from harmful substances, treating the engine oil can reduce the rate of oxidation by neutralizing acids in the oil.

Bottom Line

We hope that the advantages of engine oil additives are now clear to you. Regardless of the age of your engine, if it is corroding or requires a viscosity adjustment, there are many different kinds of oil additives available to remedy the problem. If you use the right oil additives on your engine, it will last much longer than you might think!
